Don't duplicately load modules.
Implement nqp::forceouterctx.
Add an almost-empty setting.
Remove leftover debugging code.
Set default setting and --no-regex-lib.

Means that it's now possible to just do:

    nqp nqp-jvm-cc.nqp -e "say('ok')"

And it will load the (currently almost empty) setting (which does also
bring in the MOP).
